Device for inputting title of recording medium

ABSTRACT

A device for inputting the title of a recording medium readily. When a capturing key of a tuner unit ( 1 ) is depressed, a first system controller ( 7 ) stores the text information, received currently by an FM multiplexed text broadcasting receiving tuner ( 3 ), in a capturing buffer region ( 5 B) of a memory ( 5 ). When the disc title of an MD-MO ( 11 ) is to be inputted, a title inputting mode is established, and the disc is selected as an input target unit. Thereafter, when a call key and an ENTER key are depressed, the first system controller ( 7 ) stores the captured text information in a title inputting region ( 5 C) of the memory ( 5 ) in such a way that the information corresponds to the disc which is the input target unit. Thereafter, when the ENTER key and a title inputting key are depressed, the first system controller ( 7 ) sends the contents of the title inputting region ( 5 C) to an MD recorder unit ( 10 ) and a second system controller ( 17 ) records the contents in a UTOC area of the MD-MO ( 11 ) before the ejection.

TECHNICAL FIELD

The present invention relates to a device for inputting a title of arecording medium, and more particularly to a title inputting devicecapable of facilitating a title input work for a recording medium suchas a mini disc (MD).

RELATED BACKGROUND ART

MD-MO (Magnet Optical) is one type of MD and can record and reproducedata. MD-MO can record musical tone signals in each track of a programarea. In addition, a disc title name (one name per one MD-MO) and atrack title name of each track are recorded in a UTOC (User's Table ofContents) area. During a reproduction suspension, a disc title name isdisplayed in order for a user to confirm whether the disc is a desiredone, and during a reproduction of a track recorded with musical tonesignals, the track title name is displayed in order for the user toconfirm whether a reproduced music program is a desired one. The disctitle name and track title name are not limited to an album name, analbum name manufacture name and an artist name, but may be arbitrarycharacter information which can identify a disc or a track at a glance,such as a movie title name, a portion of a music text, an explanation ofmusic, and the name of a person, a district name and a book titlerespectively not directly related to music.

An MD recorder unit for recording/reproducing data tofrom an MD-MO has atext display and a key operating unit for entering a disc title name anda track title name. The key operating unit includes a title input key,character keys (including alphabet, katakana, symbol, numeral, kanji,hiragana), a one-character delete key, a cursor key and an ENTER key.When a disc title name is to be input, the title input key is depressedto enter a title input mode. Thereafter, a track number “000” is enteredwith numeral keys to indicate that a title input target unit is a disc(the track number 000 indicates a selection of a disc title input).Then, “DISC TITLE” is displayed on the text display in a text header rowat the upper side thereof (refer to FIG. 20A), and a cursor (refer to Kin FIG. 20A) is displayed at the character start position in the firstrow of main text rows under the text header row.

If a title name “BEST HIT OLDIES/DAIICHI” is to be input, first acharacter key “B” is depressed so that “B” is displayed at the characterstart position in the first row of the main text rows of the textdisplay and the cursor moves to the second character position.Thereafter, characters “E”, “S”, “T”, “ ” (space), “H”, “I”, “T”,“”(space), “O”, “L”, “D”, “I”, “E”, “S”, “/”, “D”, “A”, “I”, “I”, “C”,“H”, “I”, and “ ” (space) are entered so that “BEST HIT OLDIES/DAIICHI”is displayed from the second character position in the first row of themain text rows of the text display to the second main text row and thecursor moves to the tenth character position in the second row of themain text rows (refer to FIG. 20B).

If the character “Q” is erroneously entered instead of the correctcharacter “O”, the cursor is returned to the tenth character “Q” in thefirst row of the main text rows by using the cursor key (refer to FIG.20C), and the one-character deletion key is depressed so that thecharacters after “Q” are moved forward by one character and thecharacter “L” is displayed at the position where the character “Q” wasdeleted (the cursor stays at the tenth character position. Refer to FIG.20D). Then, the character “O” is entered so that it is displayed between“L” and the “ ” (space) one character before and the character “L” andfollowing characters are moved backward by one character (the cursormoves to the eleventh character position. Refer to FIG. 21A). Ifcharacters “LL” are erroneously entered instead of the correct character“L” (refer to FIG. 21B), the cursor is moved to the eleventh characterposition in the first row of the main text rows by using the cursor key,and the one-character deletion key is depressed so that the eleventhcharacter “L” is deleted and the twelfth character and followingcharacters are moved forward by one character (the cursor stays at theeleventh character position. Refer to FIG. 21D). If the symbol “/” wasnot entered (refer to FIG. 21D), the cursor is moved to the characterposition “D” in the second row of the main text rows and the symbol “/”is entered so that “/” is displayed before “D” and the character “D” andfollowing characters are moved backward by one character (the cursormoves to the second character position in the second row of the maintext rows. Refer to FIG. 22A).

After all the characters are correctly entered, the ENTER key isdepressed so that the disc title name is settled and the disc title name“BEST HIT OLDIES/DAIICHI is registered in a buffer memory.

If a track title name “

” is desired for a music program at the track number 001, then “001” isentered by using numeral keys in the title input mode to select thefirst track with recorded musical tone signals as the title input targetunit, so that “TNO 001 TITLE” is displayed in the text header row of thetext display and the cursor is displayed at the start character in thefirst row of the main text rows. Then, katakana characters “

”, “

”, “

”, “

”, “−”, “•”, “

”, “−”, “/”, “

”, “

”, “

”, “−”, “

”, and “ ” (space) are entered by using character keys so that “

” is displayed in the first row of the main text rows of the textdisplay and the cursor moves to the fourteenth character position (referto FIG. 22B).

After all the characters are correctly entered, the ENTER key isdepressed so that “

” is registered in the buffer memory as the track title name of thetrack number “001”.

After the track title names for all track numbers or desired tracknumbers of MD-MO are entered in the manner described above, the titleinput key is again depressed so that the title input mode is releasedand the contents of the buffer memory are written in a UTOC memory builtin a system controller (not shown) of the MD recorder unit. Thereafter,when the power is turned off or an ejection operation is performed, thesystem controller of the MD recorder unit operates to record thecontents of the UTOC memory in the UTOC area of MD-MO before it controlsthe power-off operation or ejection operation.

When a power-on operation or loading operation is thereafter performed,the power-on operation control or a loading operation control isperformed and thereafter UTOC information is read from the UTOC area ofMD-MO and written in the UTOC memory. In accordance with the informationin the UTOC memory, the disc title name “BEST HIT OLDIES/DAIICHI” isdisplayed on the text display during the reproduction suspension. Duringthe reproduction of the music program at the track number 001, the tracktitle name “

” is displayed on the text display. Therefore, a user can confirm at aglance whether the disc is a desired one and whether the music programis a desired one.

With a conventional MD recorder unit, however, it is required to entereach character correctly by using character key in order to enter adesired disc title name or a track title name. This work is verycumbersome.

An object of the invention is to solve the above-described problem ofconventional techniques and provide a title inputting device for arecording medium capable of easily entering character information of atitle name.

BEST MODE FOR PRACTICING THE INVENTION

Next, an embodiment of the invention will be described with reference toFIG. 1. FIG. 1 is a block diagram of an audio system of this invention.

Reference numeral 1 represents a tuner unit which has an antenna 2 forreceiving a radio wave of FM multiplexed text broadcasting and an FMmultiplexed text broadcasting receiving tuner 3 (hereinafter simplycalled a “tuner”) connected to the antenna 2 for receiving a radio waveof FM multiplexed text broadcasting and outputting audio signals andtext information. It is assumed herein that the tuner 3 receives textinformation in Level 1 and outputs it. The text information includes aprogram name, a music program name, an artist name, weather forecasting,news, traffic information and the like. In Level 1, text information ofa main text is received in the unit of page and one page of the maintext is constituted of 2 rows×15 characters. Reference numeral 6represents a text display which has a display size of 2.5 rows×15characters as shown in FIG. 8. The upper 0.5 row is a text header row,and the two rows under the text header row is main text rows.

Reference numeral 5 represents a rewritable memory capable of holdingdata even when the power is turned off, such as EEPROM or a memorybacked up with a battery. The memory 5 has a display buffer region SA(refer to FIG. 12) for storing the received latest main text of one pagesupplied from the tuner 3, a capturing buffer region 5B (refer to FIG.13) for storing received text information of seven pages which a userdesignated and captured from the FM multiplexed text broadcasting, and atitle inputting region 50 (refer to FIGS. 14 to 17) to be used for aninput process of a title name of an MD-MO to be described later. Thetitle inputting region 50 has a capacity capable of storing 80characters per each title input target unit of track numbers 000 to 255.Reference numeral 4 represents a key operating unit which has: a poweron/off switch for turning on/off each block of the tuner unit 1; astation select key for selecting a broadcasting station at the tuner 3;a capturing key 4A for capturing received text information; a titleinput key 4B for turning on/off a title input mode; character keys(including alphabet, katakana, symbol, numeral and the like) forentering title name characters and track numbers 000 to 255 (tracknumber 000 indicates that the title input target unit is a disc, andtrack numbers 001 to 255 indicate that the title input target unit is atrack in which actual musical tone signals are recorded); aone-character delete key; a cursor key; a received text information callkey 4C; a next key for selecting received text information to be called;an ENTER key and the like.

Reference numeral 7 represents a first system controller made of amicrocomputer. The first system controller controls: to turn on/off apower of each block of the tuner unit 1 in response to an operation ofthe power on/off key of the key operating unit 4; to tune in a desiredstation by supplying a predetermined tuning control signal to the tunerin response to an operation of the station select key; to store thereceived latest main text information output from the tuner in thedisplay buffer region 5A of the memory 5 in the unit of page, and tocontrol the text display 6 and display the received main textinformation on the text display during an off-state of a title inputmode. When the capturing key is depressed in the off-state of the titleinput mode, the first system controller 7 writes the received main textinformation of one page stored in the display buffer region 5A, in thecapturing buffer region 5B. In this case, redundant text informationsuch as consecutive spaces in the received main text information isdeleted before the received main text information is written.

When the title input key of the key operating unit 4 is depressed, thefirst system controller 7 sets the title input mode and performs a titletext information input process of entering a disc title name of a discof the input target unit or a track title name of a track of the inputtarget unit in which musical tone signals are recorded, in accordancewith the operations of the character keys (including alphabet, katakana,space, symbol, numeral, kanji, hiragana), one-character delete key,cursor key, call key, next key and ENTER key. When the call key isdepressed, the first system controller 7 makes the text display 6display the received main text information of one page captured in thecapturing buffer region 5B, and makes the text display 6 display otherreceived main text information in response to an operation of the nextkey. When desired received main text information is displayed and theENTER key is depressed, the displayed received main text information isread from the capturing buffer region 5B and written in the titleinputting region 5C in such a way that the information corresponds to adesired title input target unit preselected by a user, either a disc ora track of one of the track numbers 001 to 255.

When the title input key is again depressed, the first system controller7 transfers the contents of the title inputting region 5C to a secondsystem controller to be descried later, and thereafter turns off thetitle input mode.

Reference numeral 10 represents an MD recorder unit. Reference numeral11 represents an MD-MO capable of recording/reproducing data, andreference numeral 12 represents a loading unit for loading/unloadingMD-MO 11 on a tray (not shown). Reference numeral 13 represents an MDrecording/reproducing unit for reproducing data recorded in MD-MO 11 andrecording data in MD-MO 11. Reference numeral 14 represents a keyoperating unit having a loading key, an eject key, a PLAY key, a STOPkey, a power on/off key and the like. Reference numeral 15 represents aUTOC memory for storing UTOC information read from an UTOC area of MD-MO11. Reference numeral 16 represents a text display for displaying a disctitle name, a track title name and the like.

Reference numeral 17 represents the second system controller made of amicrocomputer. When the power on/off key of the key operating unit 14 isdepressed, the second system controller 17 performs a power on/offcontrol for each block of the MD recorder unit 10. When the loading keyis depressed in a power-on state, the second system controller 17controls the loading unit 12 to load MD-MO 11 placed on the tray on theMD recording/reproducing unit 13, controls the MD recording/reproducingunit 13 to read the UTOC information from the UTOC area and store it inthe UTOC memory 15, and controls the text display 16 to display the disctitle name if the title name information in the UTOC informationcontains the disc title name. When the PLAY key of the key operatingunit 14 is depressed, the second system controller 17 controls the MDrecording/reproducing unit 13 to sequentially reproduce music programsrecorded in MD-MO 11 starting from the first music program (track number001). In this case, if the track title name of a track underreproduction is contained in the title name information in the UTOCinformation, the second system controller 17 controls the text display16 to display the track title name. When the STOP key is depressed, thesecond system controller 17 performs a STOP control.

Upon reception of a transfer request signal for the UTOC informationfrom the first system controller 7 of the tuner unit 1, the secondsystem controller 17 transfers the title name information in the UTOCinformation stored in the UTOC memory 15, to the first systemcontroller, and when the title name information is transferred from thefirst system controller, rewrites the title name information of the UTOCinformation stored in the UTOC memory 15. When the eject key of the keyoperating unit 14 is depressed thereafter, the second system controller17 controls the MD recording/reproducing unit 13 to record the contentsof the UTOC memory 15 in the UTOC area of MD-MO 11, and thereaftercontrols the loading unit 12 to unload MD-MO 11 placed on the tray.Also, when the power-off operation is performed, the second systemcontroller 17 controls the MD recording/reproducing unit 13 to recordthe contents of the UTOC memory 15 in the UTOC are of MD-MO 11 andthereafter performs the power-off control.

The operation of the embodiment constructed as above will be describedwith reference to FIGS. 2 to 19. FIGS. 2 to 4 are flow chartsillustrating the control operation to be executed by the first systemcontroller 7. FIGS. 5 to 7 are flow charts illustrating the controloperation to be executed by the second system controller 17. FIGS. 8 to11 are diagrams illustrating the display contents on the text display 6.FIG. 12 is a diagram illustrating the data stored in the display bufferregion 5A of the memory 5, FIG. 13 is a diagram illustrating the datastored in the capturing buffer region 5B of the memory 5, and FIGS. 14to 17 are diagrams illustrating the data stored in the title inputtingregion 5C. FIG. 18 is a diagram illustrating the record contents ofMD-MO 11. FIG. 19 is a diagram illustrating the display contents of thetext display 16.

In the off-state of the title input mode, the first system controller 7controls the text display 16 to display a header text received from FMmultiplexed text broadcasting, in the header text row. For thesimplicity of description, the description of the reception/display of aheader text is omitted. It is assumed that no data is stored at first inthe capturing buffer region 5B of the memory 5. It is also assumed thattwo music programs are already recorded on tracks of the track numbers001 and 002 of MD-MO 11 and that a track title name “

” of the track number is already recorded in the UTOC area as the titlename information (refer to FIG. 18A).

(1) Capturing Received Text Information

When the power-on operation is effected by depressing the power on/offkey of the key operating unit 4 of the tuner unit 1, the first systemcontroller 7 performs a power-on control for each block of the tunerunit 1 to make the tuner 3 enter an operation state and tune in thestation tuned immediately before the previous power-off. It is assumedherein that the tuner 3 tunes in an FM multiplexed text broadcastingstation. The tuner 3 outputs audio signals received from-an FMmultiplexed broadcasting station and outputs on the page unit basis thereceived main text information of Level 1 received from the FMmultiplexed broadcasting station. After the power is turned on, thefirst system controller 7 clears the contents of the display bufferregion 5A, sets the off-state of the title input mode, and counts on thepage unit basis the received text information in the capturing bufferregion 5B to use the count as a write pointer WP. In this case, WP=0(refer to Step S50 shown in FIG. 2). Each time the first systemcontroller 7 is supplied with the received main text information of onepage from the tuner 3, the first system controller 7 writes the receivedmain text information in the display buffer region 5A and makes the textdisplay 6 display it (refer to Steps S51 and S52, FIGS. 8A and 12A).

Consider, for example, that a CD is reproduced and broadcast and analbum name “OLDIES” of CD and a manufacture name “DAIICHI CO.” aretransmitted as the main text information of one page. In this case, thetransmission side controls the broadcasting so that “OLDIES” isdisplayed on the text display 6 in the first main text row at the centerthereof by entering a proper number of space codes before and after“OLDIES” and that “DAIICHI CO.” is displayed on the text display in thesecond main text row at the center thereof by entering a proper numberof space codes before and after “DAIICHI CO.” (refer to FIGS. 8A and12A).

It is assumed that the first and second CD music programs underbroadcasting happen to be the same as the first and second musicprograms of MD-MO 11 a user dubbed. In the example described earlier,the disc title name of MD-MO 11 and the track title name of the secondmusic program are not still entered. If “OLDIES” and “DAIICHI” aredesired to be entered as a portion of the disc title name, the capturingkey of the key operating unit 4 is depressed. In response to this, thefirst system controller 7 writes the received main text information ofone page stored in the display buffer region 5A, in the capturing bufferregion 5B at an address 0 indicated by WP (Steps S53 and S54) tothereafter increment WP by 1 (Step S55). In this case, spaces in thereceived text information other than one space immediately aftercharacters are all deleted to remove redundant character information, sothat when the received character information is used thereafter as thecharacter information of the title name, unnecessary spaces are notformed.

More specifically, as shown in the flow chart of FIG. 4, first a flag F(0: other than space, 1: space) is cleared which indicates whether acharacter code immediately before is a space or not, a characterposition m in the display buffer region 5A and a character position n inthe capturing buffer region 5B are both set to 1, and the number of allcharacter codes in the display buffer region 5A is set to L. Assumingthat the data stored in the display buffer region 5A is as shown in FIG.12A, then L=30 (Step S100 in FIG. 4). The (m=1)-th character code (inthis example, space) in the display buffer region 5A is set as “data”(Step S101). Since m=1 at the first time (YES at Step S102), the flowadvances to step S103 whereat it is checked whether the “data” is acharacter code other than the space. In this example, since thisjudgement is NO, the flag F is set to 1 without writing the data in thecapturing buffer region 5B (YES at Step S104, Step S105). Then, m isincremented to 2 (Step S106). Since m is not L+1 (NO at Step S107), theflow returns to Step S101.

At Step S101, the (m=2)-th character code (in this example, again space)in the display buffer region 5A is set as “data”. Since it is not m=1(NO at Step S102), the flow advances to Step S108 whereat it is checkedwhether “data” is a character code other than the space. Since thisjudgement is NO, it is checked whether F is 0 (Step S109). Since thisjudgement is also NO, the data is not written in the capturing bufferregion 5B, and F is set to 1 (YES at Step S104, Step S105). Since m isnot L+1 (NO at Step S107), the flow returns to Step S101.

Similar processes are repeated to the fourth character code (space) inthe display buffer region 5A, without writing the data in the capturingbuffer region 5B. At m=5, the fifth character code (“O”) in the displaybuffer region 5A is set to the “data” at Step S101. In this case, thejudgement at Step S108 is YES because the “data” is not the space. Theflow advances therefore to Step S110 whereat the “data” is written asthe (n=1)-th character code in the capturing buffer region 5 b at theaddress of WP=0, and n is incremented to 2 (refer to FIG. 13A).Thereafter, since the “data” is not the space (NO at the judgement StepS104), F is cleared and m is set to 6 (Steps S111, S106).

Returning back to Step S101, the sixth character code (“L”) in thedisplay buffer area 5A is set to the “data”. The judgement at Step S108is YES so that the flow advances to Step S110 whereat the “data” iswritten as the (n=2)-th character code in the capturing buffer region 5Bat the address WP and n is incremented to 3 (refer to FIG. 13A).Thereafter, F is cleared and m is set to 7 (Steps S111, S106).

Similar operations are repeated to the tenth character “S” in thedisplay buffer region 5A to write the “data” in the capturing bufferregion 5B, and it becomes that n=7 and m=11. Then, at Step S101 theeleventh character code (space) in the display buffer region 5A is setto the “data”. Since the “data” is the space, the judgment at Step S108is NO. However, since F=0, the next judgement at Step S109 is YES sothat the flow advances to Step S110 whereat the “data” is written as the(n=7)-th character code in the capturing buffer region 5B at the addressW and n is incremented to 8 (refer to FIG. 13A). Thereafter, since the“data” is the space (YES at the judgement Step S104), F is set to 1 andm is set to 12 (Steps S105, S106).

Returning back to Step S101, the twelfth character code (space) in thedisplay buffer area 5A is set to the “data”. The judgements at bothSteps S108 and S109 are NO so that the “data” is not written in thecapturing buffer region 5B and F is set to 1 (YES at Step S104, StepS106), to thereafter return to Step S101.

Similar operations are repeated to the seventeenth character code(space) in the display buffer region 5A and the “data” is not written inthe capturing buffer region 5B, and it becomes that m=18. Then, at StepS101 the eighteenth character code (“D”) in the display buffer region 5Ais set to the “data”. Since the “data” is not the space, the judgment atStep S108 is YES so that the flow advances to Step S110 whereat the“data” is written as the (n=8)-th character code in the capturing bufferregion 5B at the address WP and n is incremented to 9 (refer to FIG.13A). Thereafter, since the “data” is not the space (NO at the judgementStep S104), F is cleared and m is set to 19 (Steps S111, S106).

Similarly, the nineteenth to twenty ninth characters in the displaybuffer region 5A are written as the ninth to nineteenth characters inthe capturing buffer region 5B at the address of WP=0. The thirtiethcharacter space in the display buffer region 5A is not written in thecapturing buffer region 5B.

With the above processes, “OLDIES DAIICHI CO.” is sequentially writtenstarting from the top character in the capturing buffer region 5B at theaddress of WP=0. Spaces in the display buffer region 5A excepting thoseimmediately after the character other than the space are omitted (referto FIGS. 12A and 13A).

Next, while the name “

” of the second music program of CD and the artist name “

” are received and displayed as the main text information of one page(refer to FIGS. 8B and 12B), the capturing key of the key operating unit4 is depressed. In this case, the first system controller 7 writes thereceived text information in the display buffer region 5A in thecapturing buffer region 5B at the address of WP=1 (Steps S53 and S54).WP is then incremented to 2 (Step S55). Also in this case, spaces in thereceived text information other than one space immediately aftercharacters are all deleted to remove redundant character information, sothat when the received character information is used thereafter as thecharacter information of the title name, unnecessary spaces are notformed.

With the above operations, “

” are sequentially written starting from the top character in thecapturing buffer region 5B at the address of WP=1. Spaces in the displaybuffer region 5A excepting those immediately after the character otherthan the space are omitted (refer to FIGS. 12B and 13B).

(2) Setting and Reproducing of MD-MO

When a power-on operation is effected by depressing the power on/off keyof the key operating unit 14 of the MD recorder unit 10, the secondsystem controller 17 performs a power-on control for each block of theMD recorder unit (At Step S80 shown in FIG. 5). Thereafter, MD-MO 11 isplaced on the tray and the loading key of the key operating unit 14 isdepressed. In response to this, the second system controller 17 makesthe loading unit 12 perform a loading control and makes the MDrecording/reproducing unit 13 set MD-MO 11. Thereafter, the secondsystem controller 17 controls the MD recording/reproducing unit 13 toread the UTOC information from the UTOC area and store it in the UTOCmemory 15 (Steps S81 to S83). If a disc title name is contained in theread UTOC information, it is displayed on the text display 16 (StepS84). However, in this example, since it is assumed that the UTOCinformation does not contain the disc title name, it is not displayed onthe text display 16.

If it is desired to reproduce MD-MO 11, the PLAY key of the keyoperating unit 14 is depressed. In response to this, the second systemcontroller 17 makes the CD recording/reproducing unit 13 perform a PLAYcontrol to sequentially reproduce music programs starting from the firstmusic program. If the track under reproduction has the track title name,it is displayed on the text display 16 (Steps S85 and S86). In thisexample, since the track title name “

” of the first music program is recorded, it is displayed on the textdisplay 16 while the first music program is reproduced (refer to FIG.19B). When the STOP key is depressed thereafter, the second systemcontroller 17 makes the CD recording/reproducing unit 13 perform a STOPcontrol to stop the reproducing operation (Steps S87 and S88).

(3) Input of Disc Title Name

If a user wishes to input a disc title name of MD-MO 11 and a tracktitle name of the second music program, MD-MO 11 is set to the MDrecording/reproducing unit 13 of the MR recorder unit 10, and thereafterthe title input key of the key inputting unit 4 of the tuner unit 1 isdepressed. In response to this, the first system controller 7 enters thetitle input mode. The first system controller 7 transmits first atransfer request signal for the UTOC information to the second systemcontroller 17 of the MD recorder unit 10. Upon reception of the requestsignal, the second system controller 17 uses an interrupt process totransmit all title name information in the UTOC information stored inthe UTOC memory 15 to the first system controller 7. Upon reception ofthe title name information, the first system controller 7 stores it inthe title inputting region 5C in such a manner that the informationcorresponds to each of the track numbers 000 to 255 (refer to Steps S56and S57 in FIG. 2, Step S120 in FIG. 6, and FIG. 14A).

Thereafter, the first system controller 7 stands by until a track numberis entered, clears the main text rows of the text display 6, anddisplays “TNO” in the text header row (refer to Step S60 in FIG. 3, andFIG. 8C). When a user inputs “000,” with numeral keys 4B which indicatesthat the title input target unit is the disc, j=000 is written in thetitle inputting region 50 of the memory 5 to register that the titlename input target unit is the disc (refer to FIG. 14A), and “DISC TITLE”is displayed in the text header row of the text display 6. If the disctitle name corresponding to the track number 000 is contained in thetitle inputting region 5C, it is displayed in the main text rows of thetext display 6. In this example, however, since the disc title name isnot contained, it is not displayed and the cursor (refer to K in FIG.8D) is displayed in the first main text row at the first characterposition (refer to Steps S61 and S62, FIG. 8D).

If the user wishes to input a disc title name “BEST HIT OLDIES/DAIICHI”, the character key “B” is first depressed so that “B” is registered inthe title inputting region 5C as the first character of the title nametext information corresponding to the track number of j=000, to therebydisplay “B” at the first character position in the first main text rowof the text display 6 and move the cursor to the second characterposition (Steps S63 and S64). Next, “E”, “S”, “T”, “ ” “(space)”, “H”,“I”, “T”, and “ ” (space) are input so that “EST HIT” is registered inthe title inputting region 5C as the second and following characters ofthe title name text information corresponding to the track number ofj=000, to thereby display “EST HIT” at the second and followingcharacter positions in the first main text row of the text display 6 andmove the cursor to the tenth character position (refer to Steps S63 andS64, FIG. 9A and FIG. 14B).

As the next portion of “OLDIES/DAIICHI”, the already received textinformation of the text multiplexing broadcasting is used. First, thecall key is depressed. In response to this, the first system controller7 sets a read pointer RP in the capturing buffer region 5B to 0, andreads the received main text information “OLDIES DAIICHI CO.” of onepage from the capturing buffer region 5B at the address of RP=0 todisplay it in the main text rows of the text display 6 (refer to StepsS65 to S67, FIG. 9B and FIG. 14B).

After the user confirms that the displayed text information is thedesired information, the ENTER key is depressed. In response to this,the first system controller 7 writes (adds) the received textinformation in the capturing buffer region 5B at the address of RP=0,i.e., “OLDIES DAIICHI CO.” in the title inputting region 5C so that itis inserted as a portion of the title name text informationcorresponding to the track number of j=000, after the title name textinformation displayed on a disc title input screen (refer to FIG. 9A)immediately before, between the cursor position and the position onecharacter before. The text display 6 is made to resume the disc titleinput screen and additionally display “OLDIES DAIICHI CO.” at positionsfrom after “BEST HIT” in the first main text row of the text display 6to the second row, and the cursor is moved to the thirteenth characterposition in the second main text row (refer to Steps S68 and S69, FIG.9C and FIG. 15A).

If the disc title name “BEST HIT OLDIES DAIICHI CO.” is not necessary tobe changed, it can be settled by depressing the ENTER key. However, if“OLDIES” and “DAIICHI” are to be delimited by “/” (slash) and the last“CO.” is to be deleted, then the cursor is moved to the position of““(space) (start position in the second main text row) between “OLDIES”and “DAIICHI”, and the one-character delete key is depressed. Upondepression of this key, the characters after “ ” (space) are movedforward by one character both in the title name text information in thetitle inputting region 5C corresponding to the track number of j=000 andin the displayed characters on the text display 6. Therefore, “D” ismoved to the position of “ ” (space) (cursor stays at the start positionin the second main text row. Refer to Steps S63 and S64, FIG. 9D andFIG. 15B). Thereafter, “/” is input so that “/” is entered between “D”and “S” one character before “D” and the characters after “D” are movedbackward by one character both in the title name text information in thetitle inputting region 5C corresponding to the track number of j=000 andin the displayed characters on the text display 6 (cursor moves to thesecond character position in the second main text row. Refer to StepsS63 and S64, FIG. 10A and FIG. 16A).

Next, the cursor is moved to “C” of “CO.” and the one-character deletekey is depressed four times. In response to this, the four characters“C”, “O”, “.” and “ ” (space) are deleted both in the title name textinformation in the title inputting region 5C corresponding to the tracknumber of j=000 and in the displayed characters on the text display 6,and the cursor moves to the position next to “ ” (space) immediatelyafter “DAIICHI” (Refer to Steps S63 and S64, FIGS. 10B and 16B).

With the above operations, a desired disc title name is completed. Whenthe ENTER key is depressed, the first system controller 7 settles thisdisc title name as the title name text information in the titleinputting region 5C corresponding to the track number of j=000, erasesthe characters in the main text rows of the text display 6, and displays“TNO” in the text header row to thereafter stand by until a track numberis input (refer to Steps S70 and S60, FIG. 8C).

(4) Input of Track Title Name

Next, if a title name of a track having recorded musical tone signals isdesired to be input relative to the track having the track number 002 asa title input target unit, “002” is first input with numeral keys. Inresponse to this, the first system controller 7 writes j=002 in thetitle inputting region 5C of the memory 5 to register that the titleinput target unit is the track having the track number 002, andthereafter displays “TNO 002 TITLE” on the text display 6 in the textheader row. If the title name text information of the track number 002is contained in the title inputting region 5C, this information isdisplayed on the text display 6 in the main text rows. However, in thisexample, since it is assumed that the title inputting region 5C does notcontain the track title text information, it is not displayed on thetext display 16 and the cursor is displayed at the first characterposition in the first main text row (refer to Steps S61 and S62, FIG.10C).

If a user wishes to write a track title name “

”, the already received text information from the text multiplexingbroadcasting is used. First, the call key is depressed. In response tothis, the first system controller 7 sets a read pointer RP in thecapturing buffer region 5B to 0, and reads the received main textinformation “OLDIES DAIICHI CO.” from the capturing buffer region 5B atthe address of RP=0 to display it on the text display 6 (refer to StepsS65 to S67, FIG. 9B). When the user depresses thereafter the next key,the first system controller 7 increments RP by 1 to read the receivedtext information “

” from the capturing buffer region 5B at the address RP and display iton the text display 6 (refer to Steps S71 and S72, FIG. 10D).

After the user confirms that the displayed text information is thedesired information, the ENTER key is depressed. In response to this,the first system controller 7 writes (adds) the received textinformation in the capturing buffer region 5B at the address RP, i.e., “

” in the title inputting region 5C, so that it is inserted as a portionof the title name text information corresponding to the track number ofj=002, after the title name text information displayed on a track titleinput screen (refer to FIG. 9E) immediately before, between the cursorposition and the position one character before. The text display 6 ismade to resume the track title input screen and additionally displays “

” at positions from the cursor position in the main text rows of thetext display 6 to the second main text row, and the cursor is moved tothe fifth character position in the second main text row (refer to StepsS68 and S69, FIG. 11A and FIG. 17A).

If the track title name “

” is not necessary to be changed, it can be settled by depressing theENTER key. However, if “

” and “

” are to be delimited by “/” (slash), then the cursor is moved to theposition of “ ” (space) (eleventh character position in the first maintext row) between “

” and “

” and the one-character delete key is depressed. Upon depression of thiskey, the characters after “ ” (space) are moved forward by one characterboth in the title name text information in the title inputting region 5Ccorresponding to the track number of j=002 and in the displayedcharacters on the text display 6. Therefore, “

” is moved to the position of “ ” (space) (cursor stays at the eleventhcharacter position in the first main text row. Refer to Steps S63 andS64, FIG. 11B). Thereafter, “/” is input so that “/” is entered between“

” and “−” one character before “

” and the characters after “

” are moved backward by one character both in the title name textinformation in the title inputting region 5C corresponding to the tracknumber of j=002 and in the displayed characters on the text display 6(cursor moves to the twelfth character position in the first main textrow. Refer to Steps S63 and S64, FIG. 11C and FIG. 17B).

With the above operations, a desired disc title name is completed. Whenthe ENTER key is depressed, the first system controller 7 settles thistrack title name as the title name text information in the titleinputting region 5C corresponding to the track number of j=002, erasesthe characters in the main text rows of the text display 6, and displays“TNO” in the text header row to thereafter stand by until a track numberis input (refer to Steps S70 and S60, FIG. 8C).

(5) Record of Title Name in MD-MO

In this state, since there is no track number relative to which a titlename is input, when the title input key is depressed, the first systemcontroller 7 turns off the title input mode, interrupts the secondsystem controller 17, and transfers the contents of the title inputtingregion 5C. During this interrupt process, the second system controller17 overwrites the title name information in the UTOC information storedin the UTOC memory in accordance with the contents transferred from thefirst system controller 7 (refer to Steps S73 to S75 shown in FIG. 3,Step S130 shown in FIG. 7).

Thereafter, when an eject operation is performed in the suspension stateof the MD recording/reproducing unit 13, the second system controller 17controls the MD recording/reproducing unit 13 to record the contents inthe UTOC memory 15 in the UTOC area of MD-MO 11, and thereafter controlsthe loading unit 12 to unload MD-MO 11 (refer to Steps S89 and S90 shownin FIG. 5, and to FIG. 18B). If the power-off operation is performed inthe suspension state of the MD recording/reproducing unit 13, thecontents of the UTOC memory 15 are also recorded in the UTOC area ofMD-MO 11 to thereafter perform the power-off control (Steps S91 andS92).

(6) When MD-MO 11 recorded with the title names is again loadedthereafter, the disc title name “BEST HIT OLDIES/DAIICHI” is displayedon the text display 16 in the suspension state of the MDrecording/reproducing unit 13 (refer to Steps S81 to S83, FIG. 19A).Therefore, a user can confirm at a glance whether the disc is a desiredone. During the reproduction of the track having the track number 001,the track title name “

” is displayed (refer to FIG. 19B), whereas during the reproduction ofthe track having the track number 002, the track title name “

” is displayed (refer to FIG. 19C). It is therefore possible to confirmat a glance whether the music program is a desired one (Steps S85 andS86).

According to this embodiment, a user performs a title name inputoperation to input a disc title name of a disc selected as a title inputtarget unit or to input a track title name of a track selected as atitle input target unit from tracks having track numbers of 001 to 255.In this case, received text information from FM multiplexed textbroadcasting can be used as the whole or a portion of the title name.Therefore, the title name input work can be performed easily.

When text information is captured from FM multiplexed text broadcasting,redundant text information such as consecutive spaces in the receivedtext information is automatically deleted. Therefore, the displayedtitle name becomes easy to be read, and a task of deleting the redundanttext information to make the displayed title name easy to be read can beomitted. Although the maximum number of characters of a disc title nameand a track title name is limited, the title name can contain a largeamount of meaningful text information because the redundant textinformation in the received text information is automatically deleted.

In this embodiment, an album name, an album name manufacture name, amusic program name and an artist name are illustratively used as thetitle name. Instead, the title name may be arbitrary characterinformation which can confirm at a glance whether a disc or a track is adesired one, such as a movie title name, a portion of a music text, anexplanation of music, and the name of a person, a district name and abook title respectively not directly related to music.

When the first system controller 17 writes the received text informationin the display buffer region 5A in the capturing buffer region 5B whenthe capturing key is depressed, the redundant text information such asconsecutive spaces is automatically deleted. Instead, the redundant textinformation may not be deleted when the received text information iswritten, but it may be deleted at a different timing. Namely, when theENTER key is depressed while desired text information is generated fromthe received text information in the capturing buffer region 5B byoperating upon the call key and cursor key and displayed on the textdisplay 6, the displayed text information is written in the titleinputting region 5C in such a way that the information corresponds tothe current title input target unit. At this timing, the redundant textinformation may be deleted.

In the embodiment, when the redundant text information is deleted, allspaces in the received text information excepting one space immediatelyafter a character other than the space are deleted. Instead, one of thespaces sandwitched between character strings other than the space may beleft and the other spaces may be deleted, and the one left space isautomatically replaced by a delimiter symbol such as “/”.

The tuner unit 1 and MD recorder unit 10 may be formed integrally andthe first and second system controllers 7 and 17 may be realized by asingle system controller.

If the MD recorder unit has a sound record function, the UTOCinformation in the UTOC memory may be recorded on MD-MO after the soundrecord is completed.

The tuner 3 for receiving text information may be a tuner different fromthe FM multiplexed text broadcasting receiving tuner, such as a TVmultiplexed text broadcasting receiving tuner. A title name input targetmedium is not limited only to MD-MO, but other media such as a VTRcassette tape, a DAT cassette tape and a DVD-RAM may also be used.
